# isUnspecified

A Boolean value that indicates whether this instance specifies no particular grammar.

## Declaration

```swift
var isUnspecified: Bool { get }
```

## Discussion

Discussion This value is equivalent to having set none of the properties in this Morphology. This occurs when the user hasn’t specified preferences, or chose not to share them with this app. When the morphology is unspecified, inflecting a string with this morphology does nothing.
